Nanocom

Just checked mine again and it's reading high/low correctly, may have been fixed in latest software but not mentioned in list of bug fixes. I definitely have no change in throttle response but getting to the switch will have to wait until I've more time. When messing with high/low, the lever practically came away in my hand :o , think a circlip has dropped off so I need to extract the mechanism. Managed to get back into high thankfully and it can stay there for now!

Got my nanocom today and played around with it a bit.

2000MY Disco 2 auto with SLS ACE etc

Cleared my ABS faults so the four amigos went out :-)

Cleared some faults int the engine, but as i could not read the fault file without nanocom connected I have no list available right now...

Imagined or not but the engine feels smoother after that.

Went around driving a bit and played a lot but there are lots of ecu init errors. any hints?

Any experience of ABS / Power bleeding? Can I use that to bleed the brakes?

Been getting a few ecu init errors as well.

They now have all the current fuel maps (post 02) downloadable on the website.

The power balancing rpm is useful to show an injector that is playing up. Normally the figures vary from about -10 to +10. A duff injector will show a large numerical value, 35 or whatever when the others are in single digits.

If the ambient air pressure reads 0 then the ECU will not compensate for altitude. This doesn't matter much even at 5000 feet. The problem is that a new sensor is a ridiculous price, make sure you are sitting down when you ask a stealer.

Air flow is useful - it should be about 47kg/hr at idle going to over 300 under power. If it reads 0 or never changes your AFM is stuffed, which is common.

Most of the other stuff is of no real interest.

JimAttril: thank you for that!

Sent an email to nanocom day before yesterday and got a reply today. Not at all bad!

I get a lot of init errors. Is there a better way than to restart the car?

First, now the SLABS diagnostics function work just with the engine stopped, Second Nanocom was originally born for work just on the engine ECU, so the OBD port may have problem in some cars that have ground refereces of the ECUs a little higher than 0V.

We are testing an adaptor that allow the unit to have strong communication with all the ECUs. allowing also to use SLABS diagnostic when the engine runs. It will be ready in January, it will have a small price, and it doesn't require any modification, is just a small box to connect between he nanocom and the OBD cable.

Fuelling file save, how do I read the file?

You can see the content of theese files with the graphic viewer application that you find in your start menu of window, in the NANOCOM folder.

How to use this tool is described on the NANOCOM user manual.

How do I use the power bleed / ABS bleed for the ABS?

Power bleed allow to activate the ABS pump for 5 second and this give the possibility of bleed the main oil circuit to take off the air.

The modulator bleed allow to take of the air from the modulator circuit.To do that you must open the bleed screw until the oil start bleed than close the screw.Now push the pedal as srong you can and activate the modulator bleed for 3 or 4 times.Release the pedal and press it again and do again the modulator bleed function.Repeat this last points several times until the air is completely off from the circuit.

Is there documentation coming for the ABS SLS part?

Of course, it is in developement.

What is the trip function?

Trip master function.The documentation is in developement.

Best regards

Mattia

Now I've read out the codes I stored.

TD5 ECU Contain the following fauts code

3-7 air flow circuit (current)

4-1 inlet air temperature circuit (current)

9-6 EGR inlett throttle open load (logged)

9-7 EGR vacum modulator open load (logged)

13-6 EGR inlet trottle schort circuit (current)

31-2 injector 2 open circuit (logged)

31-3 injector 3 open circuit (logged)

31-4 injector 4 open circuit (logged)

When i looked at my saved fuelling file I have some peaks with high balance numbers.

Most of the time they are below 5 but the largest peak is

-21

-1

-22

17

27

for a very short time.

Is this a problem or just a temporary system glitch?

Just got a Nanocom to use with a TD5 Tomcat comp safari racer. Now looking for a fuel map to increase the power a bit. Has anyone got an improved map for a post 2002 engine?

Interestingly....

You can can't copy, or upload modified files with a Nanocom. It will only do standard files.

However... I can remap your Tomcat ;)

Ian, how would the nanocom know if a file is modified or standard?

However, you'll charge lots of money. :P

So... if I find someone who has had their flashable ecu remapped with more power, whats to stop the nanocom reading the file, and rewriting it to a different ecu?

I don't charge that much lol... and could be cheaper for a bit of advertising lol. Plus the fact I would do a map to suit your car, ECU, setup and how you want it drive.

AFAIK its something to do with the checksums within Nanocom... I just know as standard a Nanocom won't read/write a modified map.

Without being cynical, it's just a way of making more money.... especially as the only tuner that can 'offically' supply remapped files is Td5 Alive.

Hi Porny, whats special about TD5 Alive? I now have access to 2 flashed ECU's. One with an alleged 195BHP and one with 170BHP, both off racing Tomcats. I have a couple of spare NNN ecu's to mess about with.

I don't know if this is feasible, but I was thinking of starting a collection of modified maps so we can share them with other Nanocom owners?

How do you modify the map, you don't have to go in to too much detail if you don't want.

I think you may find some of the owners of the modified maps (the owners being the ones holding the copyright) might get a bit upset at people swapping them for nowt!

Well.... from what i've heard through the grapevine (and no names mentioned here), some "reputable" LR independant garages have been ripping off ECU software from chipped defenders/discos when they come in for servicing, then re-flashing others at full price.... :rolleyes::rolleyes:

The concept of copyright on modified maps is 'interesting'.

Who owns the original map? Did the modifier buy that map, then change it, in which case the modifier might own the modified map.

However, it's likely the modifier did NOT buy the original map, so how can they own the modified map, based as it is on an illegally copied original map.

Thus the first modifier cannot complain, even morally, about someone else taking and using his map, as it's what he did in the first place.

Jim's point about software security is very valid. I think you will find that Superchips maps are protected.

Jeremy Fearn told me that his maps are security coded so that his customers can't buy a tune once and use it several times.

Cheers.

It seems a bit like windoze software doesn't it.... go to eMule and there's hundreds of downloads for software, and thousands of downloads of cracks/num-generators etc to get around the security.

Interesting point David - I would be pretty sure that Land Rover didn't sell the copyright to the original map so unless the tweakers wrote their fuelling maps from scratch (which seems pretty unlikely) you are probably right. I suppose the difficulty comes with proving that they ripped off the original and then modified it, whereas it would be fairly clear if you were using a direct copy of something. Sounds like a way for lawyers to make lots of money :)

The TD5 ecu just performs a simple check sum, nothing else. Jeremy Fearn etc are talking out of the derriers when they state the map files are protected. As the ecu just performs this simple check only there is no additional protection.

The fuel map is a reference file only and there is no extra code you can insert etc to run within the ECU to validate map file against the ECU serial etc.

More likely my misunderstanding than Jeremy's misinformation. He does sell more than TD5 maps after all, via a small but international group of re-sellers.

How does the checksum work? From the factory i'm guessing the ECU's are identical for each model?

Here a link with poor translation

http://www.clublandrovertt.org/modules.php...9dcd451bb70cc03

Raw machine translated from ES to EN:

It swims then, the first thing is to choose a good male copy of frog, hihii.

The subject it I have obtained thanks to the info that has supplied Ricardo to me of JCF and as well the Italian ones of nanocom, that seem very elegant.

As very well me it has warned Ricardo, the first thing that it is necessary to take into account is that the subject is serious. We can leave so frita an Ecu as not to extract and to have to open it to return to record the flash from outside with a recorder and returning to weld. It is not very complicated, but a desoldadora SMA station and a modern memory recorder miss.

We can also load itself the motor in the case of putting a map of bad, not tested or incorrect fuel. The one that it is difficult it is that we put a map of good fuel, grafted evil and that works the Ecu and the motor is loaded, since the cheksum would not square.

The problem that has the nanocom with the maps of Ecu is that between variant of vehicle, the first 99k and map of fuel do not distinguish the following 17k. If it it makes rovacom and the curves of fuel are passed in this format.

To be able to put a curve of fuel in format rovacon in a map of nanocom, the first thing is to clean the map file of the rovacom of the bites that the rovacom includes at the beginning of the latter for its own management. These bites the rovacom them eliminates when they are moved on to the ECU. This part is between the segment 0x0 0x80 of the file of fuel. Therefore, we select this segment and us the cepillamos thing without fear. In this part I imagine that of the rovacom and the whole info of the file will be the checksum.

We read now the map of ours Ecu with the nancom. We have already a file of 117 k It we publish with the winhex and place the column of the right in ascii. We see that it begins with TD5, this part has put the nanocom to it for her account, as well as leaves than follows, but us she does not import, since we are going to leave the file in nanocom format.

The map of fuel of the ECU begins in the position 00019010 of the complete file of nancom and finishes in the 0001CFE7. The size of this segment has to coincide with the size of the file to which before it we have eliminated the piece of the Rovacom, that are 16.344 bites.

In the winhex we select the segment that goes from 00019010 up to 0001CFE7 and us the cepillamos thing again. We copy now to the clipboard the complete file of the curve of fuel to which him we had cleared the part of rovacom, and it we insert in the file of map of ECU using the edit menu clipboard it dates and grazes, in the position 00019010. In this way the file has to have the same size as before, since we have inserted a block of the same size that we have erased.

This is the one that it had already made before, but the nanocom did not swallow in this way, and it it did not eat by fault in its own cheksum. You it I commented already on Pepe, to be able to find out the cheksum of a file it is necessary to know that size has and where it is, to eliminate it and return to calculate it. And it is it has been the information fundamental that us they have passed. The cheksum of the nancom, that the not ones of the ECU that them has but them we do not touch, is in the two last bytes, and it means a simple cheksum of 16bits.

PAra to return to calculate the new cheksum, eliminate the current one, for that select both bytes last of the file of map of ECU, that as we see is preceded of characters in FF white and them we erase.

In the menu of tools of the hex win we go away to "compute hash" and it we calculate a cheksum of 16 bits. The result have to be a two bites, word. It we select and with the right button of the mouse it we copy.

We go now away to the last position of the file, the 0001D00B, and in the edit menu of winhex, we go away clipboard data and let us graze. In this way we stick the new calculated cheksum. It we stick as ascii hex and already are, I list. In the positions 0001D00C and 0001D00D in HEX what has to appear gave the calculation to us of the cheksum of 16bits.

The file has to finish in the 0001D00D and has to have a length of 118798 bytes. If it is not so, it is not valuable. In position 00019010 it has to appear in Hex 3F and Ascii "", if it is not so, bad bad, it is not valuable.

It is recorded, it is moved to the nanocom and from the nanocom to the ECU.

Eye, I have still not passed the map to the ECU because I do not have the car here, but am very probable that she works. If that it I have tested in the nancom and it works.

With this we have obtained a map of ECU keeping the variant intact and amending only the map of Fuel. That me correct the ones that they understand of Rovacom, but I believe that is this what is made, not. The variant of the manufacturer to the Ecu is put and soon the new map of fuel.

For a disk td5, which misses of fuel good it, I can pass have a map to defend do not only have am a map, it after 2002 that to whom it wanted, since me it they have given.

Much taken care, and the one that has the nanocom that she hopes that I it test, see that I happen. Until soon.

You've clearly done your homework.

If I understand you correctly, you are just using a file imported from Nanocom, replacing the block of data that contains the fuel map, recalculating the checksum and blowing it back to the ECU with Nanocom.

This needs someone to wrile a little application which does the file manipulation and checksum. Then it would only be necessary to build a library of actual fuel map blocks and insert them into the existing ECU code with the app.
